I didn't drill any holes with my system. The outside Antenna is mounted off the ladder and I routed the up into the Entertainment slide thru the same hole as the Antenna, Sat coaxes and power lines, just resealed the hole when done. So my Repeater sets in the little cubby area below the Tele.

Have a WiFi Ranger Elite AC - which is an expensive and sophisticated device. But so far, every campground WiFi has been so slow and overwhelmed that it was unusable after boosting. My opininon - don't waste your money boosting reception of something dead slow.

I have the Techno RV unit. It is mounted with ty raps on the ladder. One thing to note with all units you need a "line of sight". Last winter where we stayed i had lousy reception even with the unit. I called the tech center they asked if i could raise the antenna so attached it to the top of our flag pole. WOW what a difference. It will help from just using your lap top but you really need line of sight.

I promised a reply ~ a resounding yes to the Alfa CampPro WiFi booster from Techno RV. Please note that you can find it about $25-30 cheaper elsewhere, but if you buy it from Techno, you get both a video link and a hard copy install from Eric (owner of Techno) that makes setup very easy. If you did it with the instructions that come with the package you could probably do it but would waste a LOT of time.
Very noticeable difference in signal. yes, it will still slow down when the park is full, but at other times it saves me a lot of data on the MiFi.

WeBoost cell signal booster. If you're in the fringe areas, well worth the $$$ . Where we are we have 1 bar of signal, maybe, and slow 3G. Installed the WeBoost and we now have 2-3 bars and a pretty solid 4G. I'm happy with it.
